Magnetic resonance imaging apparatus and high radio frequency coil unit

磁共振成像装置及高频线圈单元

Abstract

The present invention relates to a magnetic resonance imaging apparatus and a high frequency coil unit for switching a plurality of coil parts with a simpler structure. According to one embodiment, the high radio frequency coil unit includes coil elements, first switching parts and second switching parts. The coil elements are arranged in a first direction and a second direction. Each of the first switching parts and each of the second switching parts are installed in a corresponding coil element of the coil elements and switch the corresponding coil element between an on state and an off state. At least two of the first switching parts are connected in series in the first direction by a first control signal line. At least two of the second switching parts are connected in series in the second direction by a second control signal line.
本发明涉及高频线圈单元及磁共振成像装置,能够通过更简单的结构来对多个线圈部件进行切换。实施方式的高频线圈单元具备多个线圈部件、第1切换器及第2切换器。多个线圈部件在第1方向和不同于所述第1方向的第2方向上排列。第1切换器及第2切换器设置在各线圈部件中,将各线圈部件分别在接通状态和断开状态之间切换。所述第1切换器通过控制用的第1信号线在所述第1方向上相互串联连接。所述第2切换器通过控制用的第2信号线在所述第2方向上相互串联连接。
